Context: No consensus exists for management of adults with congenital adrenal hyperplasia (CAH) due to a paucity of data from cohorts of meaningful size.Objective: Our objective was to establish the health status of adults with CAH.Design and Setting: We conducted a prospective cross-sectional study of adults with CAH attending specialized endocrine centers across the United Kingdom.Patients: Participants included 203 CAH patients (199 with 21-hydroxylase deficiency): 138 women, 65 men, median age 34 (range 18–69) years.Main Outcome Measures: Anthropometric, metabolic, and subjective health status was evaluated. Anthropometric measurements were compared with Health Survey for England data, and psychometric data were compared with appropriate reference cohorts.Results: Glucocorticoid treatment consisted of hydrocortisone (26%), prednisolone (43%), dexamethasone (19%), or a combination (10%), with reverse circadian administration in 41% of patients. Control of androgens was highly variable with a normal serum androstenedione found in only 36% of patients, whereas 38% had suppressed levels suggesting glucocorticoid overtreatment. In comparison with Health Survey for England participants, CAH patients were significantly shorter and had a higher body mass index, and women with classic CAH had increased diastolic blood pressure. Metabolic abnormalities were common, including obesity (41%), hypercholesterolemia (46%), insulin resistance (29%), osteopenia (40%), and osteoporosis (7%). Subjective health status was significantly impaired and fertility compromised.Conclusions: Currently, a minority of adult United Kingdom CAH patients appear to be under endocrine specialist care. In the patients studied, glucocorticoid replacement was generally nonphysiological, and androgen levels were poorly controlled. This was associated with an adverse metabolic profile and impaired fertility and quality of life. Improvements in the clinical management of adults with CAH are required.

The criteria for the diagnosis of the polycystic ovary syndrome (PCOS) have still not been agreed universally. A population of 1741 women with PCOS were studied, all of whom had polycystic ovaries seen by ultrasound scan. The frequency distributions of the serum concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and prolactin and the body mass index, ovarian volume, uterine cross-sectional area and endometrial thickness were determined and compared with the symptoms and signs of PCOS. Obesity was associated with hirsutism and an elevated serum testosterone concentration and was also correlated with increased rates of infertility and cycle disturbance. The rates of infertility and cycle disturbance also increased with serum LH concentrations > 10 IU/l. A rising serum concentration of testosterone [mean and 95th percentiles 2.6 (1.1-4.8) nmol/l] was associated with an increased risk of hirsutism, infertility and cycle disturbance. The ovarian volume was correlated with serum concentrations of testosterone, LH and the body mass index, which was also correlated with the uterine area. This descriptive data from the largest reported series of women with PCOS enables the development of a management-orientated approach to the syndrome. Women who are overweight can expect an improvement in their symptoms if they lose weight. An elevated concentration of LH (> 10 IU/l) is associated with infertility and treatment should be chosen accordingly. If the serum testosterone concentration is > 4.8 nmol/l, other causes of hyperandrogenism should be excluded.

SummaryIt is paramount that any child or adolescent with a suspected disorder of sex development (DSD) is assessed by an experienced clinician with adequate knowledge about the range of conditions associated with DSD. If there is any doubt, the case should be discussed with the regional DSD team. In most cases, particularly in the case of the newborn, the paediatric endocrinologist within the regional team acts commonly as the first point of contact. This clinician should be part of a multidisciplinary team experienced in management of DSD and should ensure that the affected person and parents have access to specialist psychological support and that their information needs are comprehensively addressed. The underlying pathophysiology of DSD and the strengths and weaknesses of the tests that can be performed should be discussed with the parents and affected young person and tests undertaken in a timely fashion. Finally, in the field of rare conditions, it is imperative that the clinician shares the experience with others through national and international clinical and research collaboration.
